As pointed out above, devices to steady a workpiece in place in a machine shop environment typically include, collectively, multiple different tools and/or machining parts that take up a significant amount of workspace. Embodiments described herein include features of a vise that may be used in a machine shop, and that may replace multiple different tools to be used in holding a workpiece in place. In one particular implementation, a vise apparatus may include at least a first jaw member having a first slip surface and a second jaw member having a second slip surface that engages in slip contact with the first slip surface. The first and second slip surfaces may be movable relative to each to each other while maintaining slip contact to apply force against a workpiece to hold the workpiece in place.

According to environment, view 100 in FIG. 1 and view 200 in FIG. 2 show features of vise apparatus. According to an embodiment, jaw piece 101 and jaw piece 102 may be moved closer together, or further apart along a dimension 204 by rotation of left right screw 105. Jaw pieces 101 and 102 each have a slip surface that engages with associated slip surfaces of jaw piece 103. As jaw pieces 101 and 102 move toward each other along dimension 204, jaw piece 103 may be translated in a direction 202 to apply a clamping force to a workpiece (not shown) against jaw piece 103. According to an embodiment, jaw piece 104 may be stationary while jaw piece 103 moves toward jaw piece 104 along dimension 202. In a particular implementation, a clamping feature 120 may be secured to jaw piece 103 and an opposing clamping feature 122 (FIGS. 5A and 5B) may be secured to jaw piece 104. According to an embodiment, clamping feature 120 may be fixedly attached to a surface of jaw piece 103. For example, clamping feature may be attached to jaw piece with screws or rivets 502. However, clamping feature 122 may be positioned in any one of multiple slots 130 depending on a desired size of a clamping cavity to match an associated workpiece of a particular size. Here, it may be recognized that, while jaw pieces 103 and 104 may have a limited maximum range of separation, movement of clamping member 122 to different slots 130 may enable securing workpieces of many different sizes to, in effect, extend a range of vise jaws.

According to an embodiment, a torque applied to left-right screw 105 in one rotational direction may translate to a force applied in direction 202 as jaw pieces 101 and 102, again having slip surfaces in contact with slip surfaces of jaw piece 103, are moved together. Likewise, as a torque is applied to left-right screw 105 in an opposite rotational direction, jaw piece 103 may be allowed to separate from jaw piece 104. As such, a force to be applied to jaw piece 103 is perpendicular to an axis of rotation upon which a torque is applied to left-right screw 105. This may allow for space savings.

According to an embodiment, a width of a slot 130 may be matched with a thickness of a flange of clamping member 122 to allow clamping member 122 to be snuggly disposed in and/or removed from a slot 130, while maintaining a secure position while clamping a workpiece in place. Clamping members 120 and 122 may include non smooth surfaces that are to be in contact with workpiece to secure the workpiece against the clamping surfaces with a static frictional force. Alternatively, clamping member 120 and or 122 may include small spikes capable of indenting and/or dimpling a surface in contact with the workpiece. This may not only assist in maintaining a position of the workpiece, but provide for easy realignment of the workpiece by matching the spikes with previously created dimples. This is shown, for example, in an implementation of FIG. 5C in which a pointed spike member 572 is disposed and secured in a bore formed in a sidewall portion of clamping member 120.

View 300 shown in FIG. 3 shows parts that may be assembled to be housed within housing 110 to, at least in part, form a vise apparatus. According to an embodiment, jaw pieces 101, 102, 103 and 104 may be formed from any suitable metal such as aluminum or steel, using one or a mixture of processes such as forging or billet machining according to dimensions and within specified tolerances. Alternatively, jaw pieces 101, 102, 103 and 104 may be formed from a carbon fiber composite and/or strengthened polymer. Slip surface 310 of jaw piece 103 may be adapted to engage slip surface 314 of jaw piece 101 while slip surface 312 of jaw piece 103 may be adapted for slip engagement with slip surface 316 of jaw piece 102. Slip services 310, 312, 314 and 316 may be polished and/or lubricated to allow jaw pieces 101 and 102 move together and separate with minimal friction as slip surface 314 moves while in slip contact with slip surface 310 and as slip surface 316 moves while in slip contact with slip surface 312.

Left-right screw 105 may be disposed through hole 318 of jaw piece 101 and hole 320 of job piece 102. According to an embodiment, exterior threading of right hand nut 106 may engage similar threading provided in hole 318 to secure left-hand nut 106 in place in jaw piece 101. Likewise, exterior threading of right-hand nut 107 may engage similar threading formed in hole 320 to secure left-hand nut 107 in place in jaw piece 102. Interior threading of left-hand nut 106 and right-hand nut 107 may be adapted to engage threading at opposite ends of left-right screw 105. Hex driver 108 may be disposed and/or fitted in right-hand nut 107, and may translate an applied torque to left-right screw 105. In a particular implementation, left-right screw 105 may be cylindrical to fit within in diameters of collars 109 and 111 to secure and may be affixed to hex driver 108 by a welding joint. Collars 109 and 111 may be attached to left-right screw 105 with a set screw (not shown) on a flat surface (not shown) or dowel pins.

According to embodiment, cavities 306 may be formed in jaw piece 104 to receive springs 304 and rod pieces 302. In a particular implementation, springs 304 may be compressed as jaw piece 103 is moved in a direction 202 as jaw pieces 101 and 102 are brought closer together (e.g., from application of a torque apply to hex driver 108). Likewise, springs 304 may expand in response to an increasing a separation between jaw pieces 101 and 102 (e.g., from application of a torque to hex driver 108 in an opposite rotational direction). As such, rod pieces 302 may be pressed against jaw piece 103 as springs 304 expand. This may allow a separation between jaw pieces 103 and 104 as the vise is opened by application of a torque to hex nut 108 to increase the separation between jaw pieces 101 and 102.

According to an embodiment, parts shown in view 300 of FIG. 3 may be disposed within a housing 110 that may be assembled as shown in FIG. 4. Here, sides 402 may bracket assembled parts of a vise (e.g., as shown in FIG. 3), and may be disposed in a parallel orientation as shown. In a particular implementation, jaw pieces 101 and 102 may abut a first side 402 while jaw piece 104 may abut a second side 402 opposing the first side 402. According to embodiment, an interface between slip surfaces of the first side 402 and slip surfaces of jaw pieces 101 and 102 may be lubricated to allow jaw pieces 101 and one or two to move closer together or further apart along dimension 204 (e.g., responsive to a torque applied to hex driver 108). Side pieces 404 and 406 may be attached so as to abut side pieces 402. In an embodiment, side pieces 404 in 406 may be fixedly attached to side pieces 402 using screws or dowel joints, just to provide a couple of examples of how side pieces of a housing may be attached to one another. Side pieces 406 may include a semicircular cut out 410 while side pieces 404 may include a semicircle cut out 408 that, in an assembled housing 110, provide a circular hole enabling left right screw 105 to pass therethrough. Sides 404 and/or 406 may be formed from steel, aluminum and/or other suitable metal using a forging and/or billet machining process with suitable tolerances. Alternatively, sides 404 and/or 406 may be formed from carbon fiber and/or a strengthened polymer. A surface of a side 402 to be in contact with jaw piece 101 and/or 102 may be polished and/or lubricated to form an additional slip surface to be in contact with corresponding slip surfaces of jaw piece 101 and/or 102. In an alternative implementation, sides 402 and 404 in combination with a base plate (not shown) may be cast formed or billet machined as a single solid piece.

FIGS. 6A, 6B, 6C and 6D are views of jaw members including slip surfaces that are sloped in two dimensions, according to an embodiment. FIGS. 6A and 6B show different views of an alternative implementation of jaw piece 101 in which a slip surface is sloped at 11.4 degrees along a direction parallel to left-right screw 105 and sloped at five degrees between edges 602 and 604 (perpendicular to left-right screw 105). An alternative implementation of jaw piece 102 (not shown in FIG. 6A or 6B) may have a similar slip surface that is sloped in two dimensions. Likewise, FIGS. 6C and 6D show different views of an alternative implementation of jaw piece 103 in which a slip surface is sloped at about 11.4 degrees along a direction parallel to left-right screw 105 and sloped at about five degrees between edges 672 and 674 (in a direction perpendicular to left-right screw 105). It should be understood that such slopes of about 11.4 degrees and about five degrees as shown in FIGS. 6A and 6B are merely examples of how a slip surface may be sloped in two dimensions, and that slopes of different amounts may be used without deviating from claimed subject matter. While slopes of jaw pieces 101 and 103 along a direction parallel to left-right screw 105 may enable translation of an applied torque to a force on jaw piece 103, slopes in a direction perpendicular to left-right screw 105 may enable stabilizing jaw piece 103 while such a force is applied to jaw piece 103. For example, slope surfaces of jaw pieces 101 and 103 may engage in a slip contact such that edge 602 of jaw piece 101 meets edge 672 of jaw piece 103 and such that edge 604 of jaw piece 101 meets edge 674 of jaw piece 103. Such an engagement of slope surfaces of jaw pieces 101 and 103 may prevent jaw piece 103 from rising as a force is applied.

As discussed in the particular implementation of FIG. 3, springs 304 and rod pieces 302 disposed in cavities 306 may return jaw piece to an open position as jaw pieces 101 and 102 are separated (e.g., responsive to a torque applied to hex driver 108). In an alternative implementation as shown in FIG. 7, slip surfaces of jaw piece 103 and either jaw piece 101 or 102 may comprise a dovetail joint that runs the length of slip surfaces that are in slip contact. For example, view 700 may comprise a cross-section view of a slip contact engagement of a slip surface of jaw piece 101 (implemented as a jaw piece 702) and a slip surface of jaw piece 102 (implemented as a jaw piece 704) forming a dovetail joint 706 running a length of the engaged slip surfaces. Slip surfaces of jaw piece 102 and 103 engaged in slip contact may similarly form a dovetail joint (not shown). As such, as jaw piece 101 is separated from jaw piece 102, dovetail joints formed by slip surfaces of jaw pieces 101, 102 and 103 may tend to retract jaw piece 103. FIGS. 8A and 8B show an alternative embodiment in which a jaw piece 801 may replace jaw piece 101, jaw piece 802 may replace jaw piece 102 and jaw piece 808 may replace jaw piece 803. Here, jaw pieces 801 and 802 each include three distinct slip surfaces meeting with corresponding slip surfaces of jaw piece 803. For example, jaw piece 801 comprises three distinct slip surfaces that engage corresponding slip surfaces of jaw piece 803 at interfaces 824, 806 and 808. Likewise, jaw piece 802 comprises three distinct slip surfaces that engage corresponding slip surfaces of jaw piece 803 at interfaces 810, 812 and 814. If jaw pieces 801 and 802 are moved toward one another (e.g., from application of a torque to left-right screw 805), a force may be applied to jaw piece 803 in a direction toward jaw piece 804 (e.g., to secure a workpiece).

As may be observed, slip surfaces of jaw pieces 801 and 802 to be in slip contact with jaw piece 803 all begin and end at the same separation from a bottom side of housing 810. As such, for slope surfaces of a particular slope angle, a force applied to jaw piece 803 (e.g., by application of a torque to left-right screw 805) may be distributed over a longer dimension. In an embodiment, multiple slip surfaces on jaw piece 801 may move in a direction 813 relative to jaw piece 803 to apply a force in a direction 811 and apply a clamping force to an opposing jaw piece (not shown). In one embodiment, jaw piece 801 may be translated bidirectionally along dimension 810 responsive to a torque applied to left-right screw 805.

FIGS. 9A and 9B provide a side-by-side comparison of features of a vise according to FIGS. 1-7 (in FIG. 9A) and a vise that translates a torque applied to an axis in a direction of force 910 to be applied to against a workpiece to hold the workpiece in place. As may be observed, features of the particular embodiment of FIG. 9A may enable implementation of a device (to secure a workpiece) that is more compact.

FIGS. 10A through 10C are views of a machine vise and workpiece secured in a rotating tombstone, according to an embodiment. A vise 1006 may be secured to a rotating tombstone 1008. According to an embodiment, features of vise 1006 may be as shown in FIGS. 1 through 8B to, for example, enable securing workpiece 1004 in place. According to an embodiment, vertical drill 1002 may be limited to application of a drill bit only in an up-down dimension. As rotating tombstone 1008 is rotated to different positions by ninety-degree increments, vertical drill 1002 may apply a drill bit to different surfaces of workpiece 1008. Here, implementing features of embodiments shown in FIGS. 1 through 8B, vise 1006 may enable securing workpiece 1004 using minimal parts and occupying minimal space.
